ROPE-SOCKET.

SPECIFICATION forming part of Letters Patent No. 792,497, dated June 13,1905.

Application filed March 10, 1905. Serial No. 249,395.

To all whom ir', mrt/y con/cern:

Be it known that I, THOMAS CANFIELD, a citi- Zen of the United States,residing at Pottsville, in the county of Schuylkill and State ofPennsylvania, have made certain new and useful Improvements inRope-Sockets, of which the following is a specification.

My invention is an improvement in that class of rope-sockets which areprovided with jaws adapted to embrace and hold the end of a rope.

The object of my invention is to provide a socket which shall bedistinguished by lightness, cheapness, strength, and security of holdupon a rope and which may be easily applied to and detached from a ropeend and any suspending device.

The details of construction, arrangement, and combination of parts areas hereinafter described` reference being had to the accompanyingdrawings, in which-- Figure 1 is a side view of my improved ropesocket.Fig. 2 is a longitudinal section of the same. Fig. 3 is a perspectiveView of one of the two duplicate members of the socket, a portion beingbroken away; and Fig. 4 is a transverse section of the socket.

The socket is composed of two duplicate members A A', each formed of asemicylindrical jaw (t, having staggered teeth b, an inwardly-projectinglug c, and a hook or curved prong CZ, the bases of the said lug andprong being extended and reinforced laterally and longitudinally, ashereinafter described, for the purpose of securing maximum strength andlightness. The lugs c project inwardly and lap upon each other and arepivoted together by means of a detachable screw-bolt @I 1When the jawsare open, as shown by dotted lines, Fig. 2, a rope end rc is inserted,and when the jaws are closed upon the rope, as shown by full lines, theteeth 7) pierce the rope at different points, and thus hold the samewith great security. Owing to the staggered arrangement of the teeth ineach jaw and in the two jaws relative to each other, each tooth has ahold independent of every other. When the jaws are closed as stated,they form a cylindrical socket which fully incloses and protects as wellas holds the rope end securely. As will be apparent by inspection ofFigs. 1 and 3, the lug o and prong Z of each member A are arrangedeccentric to the jaw a thereof, and the outer portions of the prongs areflattened on their inner sides and lie in contact, as indicated. At thebase of each lug and prong there is a lateral reinforce f, which extendsdown to and joins the adjacent end of the jaw o, and, as shown in Figs.2 and 3, the base of the lug is extended longitudinally at g on theinterior of the jaw, whereby the connection and intersupport of the twoparts is strengthened. By this construction and arrangement of parts Istrengthen the ropesocket at a point where others have usually beenweak, and hence defective, and at the same time this result is attainedwithout appreciable increase in the size and weight of the socket as awhole. As shown in Fig. 2, the end of each lug c lies when the jaws oare closed in close proximity to or in contact with the inner curvedside of the lateral reinforce f.

It will be further seen that the head and nut of the bolt e lie whollywithin the circumference of the cylindrical portion of the socket, andhence do not come vin contact with the pulleys or drums over which thesocket may pass when in use as a means for connecting the ends of a ropeused as belting. For the same reason also the contact of the bolt andnut with other objects is ordinarily avoided.

It will be further seen that the outer side of the prongs and thereinforce f thereof form a smooth symmetrical continuation of the outerside of the jaw, with which they are constructed integrally, so thatwhile great strength is obtained at that point the socket presentsexteriorly a smooth surface having no eccentric projection.

In order to attach the socket to a ring or other member forming part ofa connecting or suspending means, it is obvious that the two members A Amust bev detached from each other, which is effected by removing thebolt and nut, and that when applied, say to a ring y, as shown in Fig.2, the ring will be securely attached, and when traction is appliedthereto the hooks or prongs l are pressed outward, which throws the jawso inward or IOO toward each other and holds them securely in thatposition.

HavingI thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The improved rope-socket comprising two duplicate integral members,each consisting of a semicylindricaly jaw having staggered teetharranged interiorly, a lug extending' inwardly at right angles to thejaw, and an inwardly-curved terminal prong`r the said lug and prongbeing arranged in alinement but eccentric to the jaw, and having lateraland longitudinal extensions and reinforced, and the prongs having theirinner sides flattened, and a detachable pivot passing through the twooverlapped lugs, as shown and described.

2. The improved rope-socket, comprising` two duplicate integral memberseach formed of a scmicylindrical jaw having interior teeth for piercingand holding' a rope end, an inwardly-projecting lug and a terminal hook,or curved prong, which is in alinernent with the lug, the base of thelatter being extended at r/ on the inner side of the jaw` the exteriorbeing smooth and in the same plane with the outer side of the jaw, and aremovable pivotbolt passing through the overlapped lugs and the samelying Within the circumference of the jaws, substantially as described.
